Specification of letters Patent.

Application filed March 6, 1915. Serial No. 12,618.

To all whom it may concern:

Be it known that I, CARL E. S'rnoMotus'r, a citizen of the UnitedStates, residing at Coffeyville, in the county of Montgomery and Stateof Kansas, have invented certain new and useful Improvements inConnectors for Electric Wires, of which the following is aspecification.

My invention relates to new and useful improvements in devices forconnecting wires, the primary object of my invention being the provisionof a detachable connection for current carrying wires.

A further object of my invention consists in providing a device of theabove described character which may be operated without the employmentof any tools, only one'hand' being necessary for its manipulation.

A still further object of my invention is to construct a wire connectingdevice having contacting surfaces of large area in order that it maycarry a large current without heating. And a still further object of myinvention consists in providing means for permanently attaching theterminals of the wires to be connected to the body portions or sectionsof the device.

With these and other objects in view, my,

invention will be more fully described, illustrated in all the views ofthe drawings, and then specifically pointed out in the claims which areattached to and form a part of this application.

In the drawings: Figure 1 is a perspective view of one form of myconnection in use; Fig. '2 is a sectional view taken through both wiresand the connection; Fig. 3 is a perspective view of the members of theconnection proper, showing such members separated; Fig. 4: is an endelevation of a somewhat modified form of connection.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

My improved device for connecting current carrying wires consistsessentially of two co-acting body portions 10 and 11 which arepreferably identical in construction, as shown. Each of these bodyportions is formed from a single piece of resilient sheet metal bentintermediate its length into U- shape conformation to provide sideportions 12 and 13 connected by an intermediate or bight portion 14substantially equal in length to the thickness of the sheet metal. Asbest shown in Fig. 3 of the drawings, the free end portions of the sidesof each member bear against each other, that is, the s des convergetoward each other from the bight portion. One side portion of eachmember 1s somewhat longer than the other and has its free endout-turned, as shown at 15, to provide a cylindrical sleeve adapted toreceive the end of a wire 16, which end may be soldered or otherwisesuitably secured in the sleeve.

In use, assuming that the ends of the wires to be connected have beenproperly secured in the sleeves 15 of the members of the connection,such members are detachably joined in the manner shown in Fig. 1. Thatis, that side of each member opposite the sleeve of such member isforced between the sides of the other member, this being facilitated bythe fact that the formation of the sleeve serves to slightly space theextreme free ends of the sides of the members from each other, as shownat 17 in Fig. 3. The resiliency of the sheet metal from which themembers of the connection are formed, together with the fact thatnormally the side portions of each member engage each other, when theparts are separated, causes a firm frictional engagement of three facesof each member against three faces of the other member. It will ofcourse be understood that the size of the connection may be varied toadapt it for use with different sizes of wires and in differentcircumstances, the size of course I being increased when the wires areto carry currents of higher amperage in order that the large contactingfaces of the members of the connection shall prevent heating.

In Fig. 4 of the drawings 1 have illustrated a modified form of myinvention in cluding symmetrically formed body members l8 and 19. Thesebody members are identical in construction with the body portions 10 and11, previously described, with the exception of the wire receivingsleeves. In this latter form of my invention, the free ends of thesleeve forming sides of the body members are extended at substantiallyright angles to the body members, as shown at 20, and then bent toprovide substantially cylindrical wire receiving sleeves 21 and furtherextended, as shown at 22, in spaced relation to the portions 20. Theportions 20 and 22 are perforated to receive clamping screws 23 PatentedAprz't8, 1916.

having nuts 24' by means of which the sleeves may be contracted anddrawn into close clamping engagement with the wires which the device isto connect, thus obviating the necessity of using solder or otherfastening means. It should be noted that the nuts 24 engage bytheiredges against the sleeves 21 in such a manner as to be held againstturning movement, for which reason the wires may be readily clamped inplace by use of a screw driver or equivalent instrument.

It will of course be understood that I do not wish in any way to belimited to the specific details of construction, illustrated anddescribed, as any changes, within the scope of the appended claims, maybe made, if deemed advisable, without in the slightest degree departingfrom the spirit of my invention.

Having thus described the invention, what is claimedas new is:

1. A detachable connection for current carrying wires includingco-acting substantially U-shaped body portions, each formed from a pieceof resilient sheet metal, one side of each member being adapted forfrictional engagement between the sides of the other, and the other sideof each member being formed with a wire receiving sleeve.

2. A detachable connection for current carrying wires includingco-acting substantially U-shaped body portions, each formed from a pieceof resilient sheet metal, one side of each member being adapted forfrictional engagementbetween the sides of the I other, and the otherside of each member being formed with a wire receiving sleeve,

and means for clamping wire terminals in such sleeves.

3. A detachable connection for current carryin wires including co-actingsubstantially -shaped body portions, each formed from a piece ofresilient sheet metal, one side of each member being adapted forfrictional engagement between the sides of the other, and the other sideof each member being formed with a wire receiving sleeve, and means forclamping wire terminals insuch sleeves, said means including screwspassed through free edge portions of the sleeves, and nuts threaded uponthe screws.

4. A detachable connection for current carrying wires includingco-acting, substantially U-shaped body portions, one side of each beingadapted for frictional engagement between the sides of the other, eachbody member being formed from resilient sheet metal bent intermediateits length to provide side portions spaced at their connected ends adistance substantially equal to the thickness of the sheet metal andhaving their sides converging toward each other from such connected end.

5. A detachable connection for current carrying wires includingsubstantially U- shaped body members each formed from a piece ofresilient sheet-metal, one side of each member being adapted forfrictional engagement between the sides of the other, and the other sideof each member being formed with a wire receiving sleeve disposedparallel to the bight portion" of the body.

6. A detachable connection for current carrying wires includingco-acting substantially U-shaped body portions, each formed from a pieceof resilient sheetmetal, one

side of each member being adapted for frictional engagement between thesides of the other, and the other side of each member wardly toward thefree end of the first side to form a wire receiving sleeve.

In testimony whereof I aflix my signature in presence of two witnesses.
